JULIAN KENNEDY, F PITTSBURGH, PENNSYLVANIA APPQBATUS FOR ROLLING $HEETS Application filed January 19, 1929. Serial No. 383,634.

is passed through successive roll stands, is

1Q mechanically supported between stands, the

' material being free of a stand be ore enter-- ing a succeeding stand, and is guided into the stands by hand. By this method a large percentage of the labor cost required in hand mill operation is eliminated, the work of the roller is made much easier, theinstallation cost is reduced to a minimum, and the product may be rolled at high speeds. In that application there is specifically described a mill wherein the several stands are arranged in a substantially straight line. As pointed out therein, it is important that the workmen be so positioned that they may stand in substantial alinement with the travel of the material into a stand whereby they can most effectively guide it. For this purpose there are provided in the apparatus described in said application platforms extending over the supporting tables.

In the present invention, thestands, instead of being :arranged in a straight line, are laterally oliset, and the supporting tables extend therehetween insuch manner that a workman may stand'alongside the table and guide the sheets into a pass. For convenience of arrangement, I preferably place .the successive stands in a zig-zag ar-' rangement, the several stands lying in two crably extend for a short distance from the natcs in a stop whereby the material'may rows but being, staggered. "The tables pref be S% ared up before it passes into the next stan With this arrangement a considerable degree of freedom of movement is available to the roller. He may stand at a somewhat lower level relative to the roll tables than is the case in the app ratus described in my, eopending application above identified and there is no necessity for shielding him much from the heat of the rolls, as he is not positioned with his back ve close to a stand and in alinement therewit but on the contrary stands alongside the mill. i

The accompanying figure of drawing is a top plan view of four stands of a'mill embodying my invention.

The mill illustrated in the drawings comprises successive stands numbered 2 to 5 inclusive, it being understood that as many stands as required will be provided. "The bottom roll of each stand is driven by a motor 6, the top rolls being undriven.

Between the stands 2 and 3 there is provided a table comprising a portion 7 extending in substantial alinement with the path of travel of the material as it issues from the mill stand 2, and a portion 8 extending at sub stantially right angles thereto. The table 7 portion 7 comprises side rails 9 and roller shafts 10. A sheet bar is fed between the rolls of the stand 2 and the issuing material is supported by the roller shafts 10, the sheet movin forward onto the table portion 8. In thista le portion 8 there are provided driven rolls 11 which move the material sidewise,

in the direction of the arrow, until it strikes a stop 12. A workman stands at the point W and grasps the material with a pair of ton to feed it into the rolls of the stand 3. e squares the material before feeding it to the rolls, being-assisted inthis operation by the stop 12. r

As the sheet issues from the stand 3 it passes 7 over a table portion 13, similar in all respects to the table portion 7, and thence moves onto a table portion 1 L corresponding to the table portion 8. A second workman stands at the point VVl and feeds the material into the stand 4. The stand 4 is in alinement with the stand 2 and material issuing therefrom is carried on a supporting table identical with that lying between the stands 2 and 3 and is effective for carrying the material to a point where a workman standing at W2 may feed it to the rolls of the stand 5.

In practice as many stands as are required for giving the desired number of passes are provided, these mills lying in spaced'rows as illustrated in the drawing. After a sheet bar has been given a desired number of reductions, the formed sheet is paired with another sheet and the operation continues.

I have illustrated and described the present preferred embodiment of the invention, but it will be understood that it is not limited to the form shown as it may be otherwise embodied within the scope of the following claims.

I claim:

1. Apparatus for rolling sheets comprising a plurality of stands, the stands being laterally offset relative to one another, and tables extending between "the stands, the tables being so positioned and arranged that a workman standing alongside a table may engage material thereon and feed it into astand.

2. Apparatus for rolling sheets comprising a plurality of laterally offset stands in zig-' zag relation, and tables extending between the stands, the tables and stands being so arranged that the material is moved sidewise after different passes to align it with the succeeding stands.

3. Apparatus for rolling sheets comprisin a plurality of laterally offset stands arrange in two rows, the stands being staggered, successive stands lying alternately in different rows, and tables extending between a stand in one row and a stand in the other row.

4. Apparatus for rolling sheets comprising a plurality of stands, the stands being laterally" offset relative to one another, and tables extending between the stands, a table comprising a portion lying at the exit side of a stand and extending in the direction of travel of material as it leaves such stand, and a second portion extendin at substantiall right angles thereto, the ta les being so-positioned and arranged that a workman. standing alongside a table may engage material thereon and feed it'into a stand.

5. Apparatus for rolling sheets comprising 'a plurality of stands, the stands beirig laterally offset relative to one another, and tables extending between the stands, a table comprising a portion tlying at the exit side of a stand and extending in the direction of travel of material as it leaves such stand, and a second portion extending at substantially right angles thereto and terminating in front of another stand, the tables being so positioned- 11nd arranged that a workman standing alongside a table may engage material thereon and feed it into a stand. v 6. Apparatus for rolling sheets comprising meaiea a plurality of stands, the stands being laterally ofiset relative to one another, and tables extending between the stands, a table comprisin a portion lying at the exit s ide of a stand and extending in the direction of travel of material as it leaves such stand, and a second portion extending at substantially right angles thereto, the second portion of said table having driven members arranged to convey material therealong, the tables being so positioned and arranged that a workman standing alongside a table may engage material thereon and feed it into a stand.

7. Apparatus for rolling sheets comprising a plurality of stands, the stands being laterally oitset relative to one another, and tables extending between the stands, a table comprising a portion lying at the exit side of a stand and extending in the direction of travel ofi material as it leaves such stand, and a second portion extending at substantially right angles thereto, said second portion terminat ing in a stop whereby the material may be squared, the tables being so positioned and arranged that a workman standing alongside a table may engage material thereon and feed it into a stand.

In testimony whereof I have hereunto set my hand.
